I washed ours on a delicate cycle and used Oxyclean on the water stains. They came out like new. I washed them and then tossed them in the dryer for maybe 15 minutes. I hung them back up while still damp. I just wanted to dry them long enough to get the wrinkles out.
I might add, ours are in a 1998 Bounder, and as far as I know, they are the original drapes. I've washed them 3 or 4 times in the 4 years we've owned it. I was worried due to their age, but they are fine.
The velcro was bad on them, where they join together in the front. That had nothing to do with laundering them, though. I finally replaced the velcro and they are good to go again.
